Limp home mode light will come on and stuttering

For the last couple months my 2005 f150 5.4L v8 will have the limp home mode light come on and stutter as i am driving down the road. as i press the gas the stuttering gets worse. i had the codes read and was told it was an electrical short in the wiring harness to the throttle positioning sensor. had the harness read out and everything checked fine. is there anything else i can check?

Check the actual ohm readings for tps sensor to manufacturer specs. Sounds like the tps sensor is out of range. Sometimes the o2 sensor gives a false reading to the ecm which causes the tps malfunction. Doubt seriously if it electrical short. Bad ground maybe.

My 1998 dodge durango slt wont drive past 40 miles an hour


Hello Jeff Winner,

Over the last 20 years ... cars have has a LIMITED OPERATION FEATURE added... When the engine READS something that is not IMMEDIATELY catastrophic... it will allow you to
LIMP home... rather than a complete shut down.

Limp mode:
You SHOULD also have a CHECK ENGINE light... (?)

My best advice is to limp on down to your near-by FREE code reading shop... and have a READER tell you what CODES are registered...

A blocked exhaust system will also seriously SLOW your progress
((soon to stop all-together)).

Hope this helps

Check you exhaust prices BEFORE you go...!!

05 mini cooper S went into limp home mode, warrning lights blinking, shut off and re-started. Stopped for a bit then back into limp home ? what might be causing this


Look in the owners manual

There is usually only a couple choices
when you go into Fail Safe

ETC Fail Safe -- for ignition problems,to protect the converter
Overheating Fail Safe
Transmission Limp Mode or Overheat

Just examples
Don't know your vehicle systems

Check for codes as ALWAYS WITH ALL
VEHICLE PROBLEMS first thing you do,
don't need to ask any questions

Check for codes-- then google them

LIMP MODE HOME


The O2 Sensors need to be changed at 100,000 miles,
before they fail & you get a MIL Lamp on your dash

Just the front (2) closest to the engine, at the converter inlet

The ETC Failsafe, is most likely bad COP ignition coils
Have to check for cylinder misfire count with a professional
scan tool in Mode #06,unless you want to spend a few days
walking a new coil from one cyl to the next

Always provide V6 or V8 in your question & lots of detail

2002 Impala: transmission limp mode...


Most transmissions have a limp mode, or limp-home mode.
If the driveline computer thinks there is something wrong, it can lock the transmission into one gear, such as 2nd gear. Usually reverse will also be available. The Impala automatic has 4 speeds. 2nd speed or gear will get you home, but the engine rpms can get a little high. I wouldn't get on the expressway will in limp mode.
Before taking to the shop, you might want to try and reset limp mode by turning the car off for a couple minutes, or you may have to disconnect and reconnect the battery.

Subaru 96 Gt Wagon Has Gone Into limp mode whats the problem?


When was the last tune? May have fouled plug (s) which is causing that mis fire, hesitation and stuttering. Need to have is scanned with code reader to find out which cylinders are not firing. This will assist you in isolating the problem. the scan could very well tell you to look at the flow meter.

Wrench light


It may be that your TPS (Throttle Position Sensor) is bad or dirty. Try cleaning it, and if that doesn't work, then replace it. It goes for about $45, but if you take it to the stealership they'll run you over $200.
I had the same problem and got it fixed. Takes a couple of minutes.
